Indima yezixhobo zomthi weKrisimesi kwi-drilling wellheads
Njengoko ixesha leeholide lisondela, abantu abaninzi baxakekile behombisa imithi yabo yeKrismesi kwaye bangena kumoya weholide. Kodwa ngaba ubusazi ukuba igama elithi "umthi weKrisimesi" likwasetyenziswa kwishishini leoli kunye negesi ukubhekisa kwizixhobo ezibalulekileyo ezisetyenziswayoukugrumba amaqula ? Kule blog, siza kuphonononga indima yeIzixhobo zomthi weKrisimesikwindawo yokugrumba kunye nendlela eqinisekisa ngayo ukukhutshwa okukhuselekileyo nokusebenzayo kwe-oyile kunye negesi.
Umthi weKrisimesi, obizwa ngokuba yi-aintloko kakuhle, yindibano yeiivalve , iispools, kunye nezinto ezifakwe phezulu kwiqula ukuze kulawuleke ukuhamba kweoli kunye negesi yendalo equleni. Iyingxenye ebalulekileyo yezixhobo ze-wellhead kwaye idlala indima ebalulekileyo kwimveliso kunye nokugcinwa kwemithombo yeoli.
Omnye wemisebenzi ephambili yomthi weKrismesi kukulawula ukuhamba kwamanzi equleni. Oku kufezwa ngothotho lweevalvu ezinokuvulwa okanye zivalwe ukulawula ukuhamba kwe-oyile, igesi yendalo, kunye nolunye ulwelo olusuka kumthombo. Umthi weKrismesi ukwabonelela ngokufikelela kwiqula ukwenzela ulondolozo kunye nemisebenzi yongenelelo, evumela abaqhubi ukuba benze imisebenzi efana nokuvavanya amaqula, ukusebenza ngocingo kunye nokuqhekeka kwehydraulic.
Imithi yeKrisimesi idla ngokuxhotyiswa ngeevalve ezahlukeneyo, kuqukaiivalve eziphambili,iivalve zamaphikokwayeiivalve ze-throttle , ukulawula ukuhamba kwamanzi kunye nokuvala iqula kwiimeko ezingxamisekileyo. Ezi zivalo zisebenza ngokude ukusuka kumphezulu usebenzisa inkqubo yokulawula, evumela abaqhubi ukuba babeke iliso kwaye balawule ukuhamba kwamanzi ukusuka emthonjeni ngaphandle kokufuna ukufikelela ngokomzimba kwi-wellhead.
Ukongeza ekulawuleni ukuhamba kwamanzi, umthi usebenza njengendawo yokudibanisa izixhobo ezahlukeneyo ezifana ne-tubing yokuvelisa, i-casing hangers, kunye nezixhobo zokulawula uxinzelelo. Oku kuvumela i-oyile nerhasi ukuba iveliswe equleni ngokukhuselekileyo nangempumelelo, ngelixa ikwabonelela ngeendlela zokubeka iliso kunye nokulawula uxinzelelo kunye nobushushu bomthombo.
Uyilo kunye nokusebenza kwezixhobo zomthi weKrisimesi kubalulekile ekuqinisekiseni ukhuseleko kunye nokuthembeka kwequla. Isixhobo kufuneka sikwazi ukumelana noxinzelelo oluphezulu, ulwelo oludlekayo kunye namaqondo obushushu agqithisileyo ngelixa sisabonelela ngolawulo oluthembekileyo noluchanekileyo lokuhamba kolwelo equleni. Oku kufuna ukuyilwa ngononophelo kunye nokuveliswa ukuqinisekisa ukuba umthi unokumelana neemeko ezinzima zomthombo.
Isishwankathelo, izixhobo zomthi weKrisimesi zidlala indima ebalulekileyo kwi-drilling wellhead, iqinisekisa imveliso ekhuselekileyo neyiyo ye-oyile kunye negesi. Imithi yeKrisimesi iyingxenye ebalulekileyo yezixhobo ze-wellhead ngokulawula ukuhamba kwamanzi, ukubonelela ngokufikelela kwimisebenzi yokugcinwa kunye nokungenelela, kunye nokukhonza njengeendawo zokudibanisa izixhobo ezahlukeneyo. Ukuyila kunye nokusebenza kwayo kubaluleke kakhulu ekuqinisekiseni ukhuseleko kunye nokuthembeka kwequla, okwenza kube yinto ebalulekileyo kwimpumelelo yokusebenza kweoli kunye negesi.
